7 Claims.

invention relates to spinning frames, and more particularly to an improved picker for removing lint accumulating adjacent the spindle.

` .An object of this invention is toprovide a picker forlint which can be easily and quickly coupled to the spindle, the picker including an elongated eirible shaft so that theneedle may be engaged with adjacent parts ofthe spinning frame for picking up lint or other fibrous material. Another object of this invention is to provide a picker of this kind which is coupled directly to a spindle and `operated thereby. A

A further object of this invention is to provide a picker of this kind which includes an improved normally released clutch sothat the picking needle may be optionally operated and can be quickly .i cleaned without decoupling the device from the. spindle.

y Withthe above, and suchv other objects in View as may hereinafter more fully appear, the invenftion consists of the novel construction, combination and arrangement of parts as will be more specifically referred to and illustrated 'in the accompanying drawing,` wherein are shown embodiments of theinvention, but it is to be understood that changes, variationsand modications may be resorted to which" `fall within the scope of the invention", 'as c'zlairned'.`

With the above and such other objects in view as may hereinafter more fully appear, I have invented the device shown in the accompanying drawing, in which:

Figure 1 is a fragmentary side elevation, partly insection, of a spinning frame having mounted thereon a picker constructed according to an embodiment of this invention.

Figure 2 is a fragmentary longitudinal section of the innerend of the device.

Figure 3 is a fragmentary longitudinal section of the outer or needle end of the device.

Figure 4 is a sectional view taken on the line Figure 5 is sectional view taken on the line 6-5 of Figure 1.

Referring to the drawing the numeral I designates generally a spinning frame, which has rotatably mounted thereon 'a plurality of spindles I I, carried by a rail I2 and rotated by means of a flexible belt I3. The spinning frame I0 also includes a long draft system of rollers, generally designated as I4, and thread or yarn guide members I are hingedly secured as at I6 to a supporting bar or rail I1. There is a thread guide I5 for each spindle II, and these guides may be swung upwardly as shown in Figure 1, to an inoperative position( During the winding of the yarn or thread on the bobbin or other element engaging the spindle Il, a considerable amount of 'lint drops from the yarn and unless this lint is Periodically removed it frequent.y s picked upby the yarn as the latter is triangular in transverse section. The needle I8 includes a rounded shank I9, which is journalled inra pair of bearings ZIland 2l carried by the opposite legs 22 and 23 respectively of a U- shaped support 24. The U-shaped support 24 is formed integral with or secured to an elongated resilient arm or strap 25, which is provided with a reverted portion 26 secured by fastening members 2l to a hollow handle 28. The round shank I9 has secured theretoa roller 29 and this roller is normally disposedin spaced relation to a driving rollerf30 secured toa rotatable shaft 3I. The shaft 3`I is -jour'nalled 4in anti-friction bearings 32 Vand 33 disposed in a bore 34 formed in a bearing member 35. Thefshaft3l is" formed with a polygonal opening 36 at its inner end 'Within which the polygonal end 31 of a flexible shaft 38 is adapted to removably engage.

The shaft 38 is rotatably disposed in a flexible sheath 39 which is extended through an opening 4U formed in the inner end of the handle 28 and the sheath 39 is also extended into an opening 4I formed in the bearing 35. A set screw 42 is threaded through bearing 35 and engages sheath 39 so that it will hold the sheath in the bearing 35 and retain the shaft 38'in the recess or opening 36.

A bored plug 43 is threaded into the outer end of the bearing 35 and provides a means for retaining a lubricant in the bore 34.

The shaft 38 and the sheath 39 are of substantial length and have secured to the opposite ends thereof a housing 44. The housing 44 is of cylindrical construction and has rotatably mounted therein a shaft 45. The shaft 45 is .iournalled through a pair of anti-friction bearings 46 and 41 disposed in the housing 34, and the shaft `45 is formed with a polygonal socket or recess 48 within which the polygonal inner end 49 of the shaft 38 removably engages.

' A sleeve 5U is secured to the sheath 39, and is formed with a flanged lower end 5I adapted to towardV the small end thereof.

engage against the inner end of the housing 44. An apertured or ilanged cap '52 is threaded on the upper end of the housing 44, and bears against the anged lower end 5I of the sleeve 5B, so as to tightly hold the sheath 39 with respect to the housing 44.

The shaft 45 has secured thereto below the housing 44,` a knurled wheel 53 by means of which the shaft 45 may be grasped in one hand so as toyhold the shaft against rotation while a chuck 54 which is threaded on the lower end of shaft 45 is adjusted to either clamp or release the chuck from the spindle I I.

In order to provide for holding the housing, 44 against rotation when the chuck 54 is engaged with a spindle Il, I have provided a laterally projecting arm 55 which isfsecured as at 56 to thehousing 44. Thearm 55 isadapted to engage against one side of a thread guide I5, which is in operative position so as to therebyr hold housing 44 against rotation.

` In theuse and operation of this device-the chuck 54 is clamped to spindle II, one of the thread or Vyarn guides I5 being swung upwardly to permit the :housing 4'4 to engage between a pair of adjacent thread guides Vassociated with ladjacent` spindles. A handle or housing 28 is grasped in one hand, the hand engaging about the needle carrier arm 25. Arm 25 may be swung inwardly ltoward handle or housing` 28 thereby bringing roller 29 into engagement with driving roller '30. -Needle I8 will thereupon rotate and this needle may be projected about the desired parts of the spinning frame soA as to wind loose yarn thereabout. When it is desired to clean the needle,roller carrying arm 25 may be released'sothat rocker 29 will be disengaged from roller 3U. The needle I8, being of tapered construction, will permit ready removal ofv the lint lI'clair'n: v LA pickerfor connection with and operation bya spindleof a spinning frame comprising a flexible shaft,a picking needle at one end of said shaft anda chuck secured -to the opposite end'of said shaft and adapted to grip said spindle for ro;
